In a collection of research papers devoted to the problem of solar variability and its origin in planetary beat, it is demonstrated that the forcing function originates from gravitational and inertial effects on the Sun from the planets and their…
On 7 January, 2014 at 18:32 GMT, the Sun unleashed a massive X1.2-class solar flare, seventimes the size of the Earth (NASA News, 2014b). At the occasion there was a strict triple inferior conjunction of Jupiter, Earth and Venus with…
Herein I discuss common errors in applying regression models and wavelet filters used to analyze geophysical signals. I demonstrate that: (1) multidecadal natural oscillations (e.g. the quasi 60 yr Multidecadal Atlantic Oscillation (AMO), North Atlantic Oscillation (NAO) and Pacific Decadal Oscillation…
Close examination of the small perturbations within the atmospheric CO2 trend, as measured at Mauna Loa, reveals a strong correlation with variations in sea surface temperatures (SSTs), most notably with those in the tropics. The temperature-dependent process of CO2 degassing…
The Intergovernmental Panel on Climate Change (IPCC) attributes observed climate variability primarily to anthropogenic CO₂ emissions. This conclusion relies heavily on adjusted datasets and outputs from global climate models (GCMs) within the Coupled Model Intercomparison Project (CMIP) framework. However, this…
We briefly review the dominant role of clouds in Earth’s climate. The earliest observational studies of heat transfer through Earth’s atmosphere, for example, those of John Leslie around 1800, showed that clouds have a large effect on radiative heat transfer…
I gave a short introduction to the climate conference in Mölndal 26-27 October 2024. The theme of the conference was “Science and Politics” so I picked up a couple of basic philosophical words of wisdom for this occasion. The first…
The idea that our climate reacts differently to anthropogenic forcings than to natural instabilities through the phenomenon of “feedbacks”, seems widespread. This paper shows that climate feedbacks are not effects induced by forcings, but in fact “constitute” our climate. Independent…
In this study we investigate the impact of greening on the Earth in terms of gross primary production (GPP) on the natural atmospheric CO₂ level. The total mass of CO₂ in the atmosphere is equal to the yearly amount of…
Using a detailed atmospheric radiative transfer model, we derive macroscopic relationships of downwelling and outgoing longwave radiation which enable determining the partial derivatives thereof with respect to the explanatory variables that represent the greenhouse gases. We validate these macroscopic relationships…
The white paint or white plastic of the housings of weather stations ages, which leads to increased absorption of solar radiation and to increased temperature measurements. This alone would be a small error. However, many different state-of-the-art homogenization algorithms repeatedly…
The impact of certain factors on the changes in atmospheric carbon dioxide (CO₂) concentrations has yet to be elucidated. In particular, the impacts of sea surface temperature (SST) on the balance of CO₂ emissions and absorption in the atmosphere and…
The late Ernst Georg Beck wrote a rather controversial but very interesting article titled “Reconstruction of Atmospheric CO2 Background Levels since 1826 from Direct Measurements near Ground “, published in this journal (Beck, 2022) that raised several comments, the most…
For many years, the scientific debate about the threat of rising global temperatures caused by rising atmospheric carbon dioxide concentration has depended on estimation, homogenization, the use of anomalies rather than actuals, and complex computer modelling of key variables. This…
Volume 4.1 When the Royal Swedish Academy of Sciences awarded part of the 2021 Nobel Prize for Physics to Syukuro Manabe they failed to recognize that the climate models used to justify the award were invalid. When the CO2 concentration…
Vol 4.1 According to the paradigm of the IPCC global warming is solely due to anthropogenic causes. Record-high temperatures have been measured for the summer months of 2023 and the anthropogenic climate drivers – mainly greenhouse gases – have been…
